A neural network method and device are included, A neural network circuit includes a synaptic memory cell including a resistive memory element, which is disposed along an output line and which can have a first resistance value and a second resistance value as a resistance value, the synaptic memory cell generates a column signal, based on the resistance value of the resistive memory element and an input signal received via an input line, a reference memory cell including a reference memory element, which is disposed along a reference line and which has a resistance value that is a ratio of the first and second resistance values, the reference memory cell generates a reference signal, based on the resistance value of the reference memory element and the input signal, and an output circuit generates an output signal for the output line based on the column signal and the reference signal.

Neural network based method and device

A transmitter includes: a pulse amplitude modulation encoder that encodes serial data to multi-bit transmission data of a first data group and a second data group; a first driver that converts first multi-bit transmission data of the first data group to a first differential signal having a first voltage swing width; a second driver that converts second multi-bit transmission data of the second data group to a second differential signal having a second voltage swing width narrower than the first voltage swing width; a first voltage regulator that provides to the second driver a first low swing voltage for generating the second differential signal; a second voltage regulator that provides to the second driver a second low swing voltage less than the first low swing voltage; and a constant current load switch that provides a current path between the first and second voltage regulators depending on deactivation of the second driver.

Pulse amplitude modulation transmitter and pulse amplitude modulation receiver

A phase-rotating phase locked loop (PLL) may include first and second loops that share a loop filter and a voltage controlled oscillator in order to perform the operation of a phase-rotating PLL, the first and second loops configured to activate in response to an enable signal. The PLL may further include a phase frequency detection controller configured to provide the enable signal to the first and second loops in response to a transition of a coarse signal that may be applied as a digital code.
